10 Fig. 2 is a plan view of the base of Fig. 1;

Fig. 3 is a section on the line IIIIII, Fig. 2; Fig. 4 shows anembodiment of the invention as a base for a flare;

Fig. 5 is a fragmentary perspective view of the 15 device in a partiallytilted position; and

Fig. 6 is a View of the knock down cluster for the device.

Iron casting l is shown with flat base 2 having central countersink 3from such under side. 20 Radiating from this central mass. of thecasting is a plurality of arms t having under side 5 up wardly curved ortapering as a contributing factor toward self-righting. This casting lacross the top has diverging seats 6 intersecting at cen- 25 tralopening i. In these seats 6 are mounted fender arms having central flatportions 8 and riser portions 9 to terminal oiisets ill. These fiatportions 8 intersect and have central open ings ll, through which mayextend central stem 30 I2 having collar l3, and therebelow threadedportion M, with which may engage wing nut l5 in effecting detachableclamp assembly of these major fender arms with the base and its minorarms 4.

35 In the preferred set-up herein, the seats 6 in their extent from thecentral opening I locate the arm termini Ill in unsymmetrical relationas to the arms t, thereby promoting tendency, when a terminus of an armI" is oriented down, to have the counterweight of the mass shift to oneside therefrom instead of being balanced thereabout. This is aneffective unbalanced design insuring such rolling away from an arm 10 toan arm 4 with thereby promotion of further 45 rolling towardself-righted position to rest on the bottom 2 of the base.

The center of gravity is normally in the base I for self-righting ofstandard l2 in carrying flag or pennant It. The showing herein is of a50 collapsible small-space-taking device adapted to be carried by trucksand busses. It will take but little space, may be quickly assembled, andcan be positioned as desired along a highway or in spaced relation fromthe object to be protect- 55 ed, or as might be special warning say forpainting a highway, patching, rupture, or some hazard even as towash-out or opening in ice as a warning to skaters. The passing trafficor heavy gust of wind may have a tendency to overcome the mass, but atonce such is past, even though there be a tendency to rock so far asdown position for the standard, there is at once a resetting back to theupright.

In this tool, with standard I2 removed, the riser portions 9 may providea central seat in which may be located receptacle i1 having burner it tooperate as a flare signal for night use, while the flag l5 may beeffective in the daytime or as visible.

- What is claimed and it is desired to secure by United States LettersPatent is:

l. A tiltable base, and fending arms upward from the base providing aseat adapted approxi mately centrally intermediate said arms to supportan object in upstanding position of the base, said fending arms on basetilting providing fulcra for base return against overthrow of theobject.

2. A tiltable base having minor radially extending arms adjacent andparallel to the plane of rest of the base, detachable major radiallyextending fending arms upward from said base minor arms, said baseproviding a seat adapted centrally intermediate said arms to support anobject in upstanding position, said fending arms being adapted to coactas fulcra for base return to the plane of rest.

3. A knock down pack of a self-righting standard device embodying aradiating-arm-carrying base, a plurality of attachable radiating fendingarms mounting the base in pairs upwardly from the plane of rest of thebase providing in annular series fulcra in unsymmetrical radial relationand promoting self-righting return of the base, and assembly means forthe fending arms in providing seat means for an object to be supportedapproximately concentrically of the base.

l. A tiltable multiple arm metal base providing a seat approximatelycentrally thereof, the arms of said base having greater extent radiallyaway from the bottom of the base, there being diverging seats on thebase, terminally offset U- shaped fending arms on said diverging seatsupwardly from the plane of rest of the base, and a stem clamping saidfending arms to the base at the central seat, said stem being adapted toextend upward to provide a standard for a traflic signal, said fendingarms being in annular series in different planes approximately parallelto the base and in pairs in position of unbalance therebetween as wellas unbalance by the base for tilting on the base toward rightingposition.
